Summary

The purpose of this subject is to outline to students the principles of
prevention and repression of spontaneous combustion in coal mining. It is based on information about early detection of spontaneous heating of coal, suppression measures like application of nitrogen and the main methods of fighting of mine fires.

Subject syllabus:

The course deals with one of the most serious risks of coal mining - issue of endogenous fires, their prevention and repression. The main circuits subject in the prevention of spontaneous combustion include chemical and physical properties coal substance, the theory of spontaneous combustion, methods for assessing the susceptibility of coal matter of spontaneous combustion, the statistics of endogenous fires in coal OKR underground mines, natural and technical factors influencing the formation endogenous fires, early identification of spontaneous combustion (gas indicator, infratechnologie), principles of prevention of spontaneous combustion in mines, aerodynamice of goafs, the application of technical means spon-com prevention (inhibitors, nitrogen, sealing falls, depression, regulation etc.). In the area of repression is the main subject of the control circuits of mine fires intervention order mine rescue. Training courses are supplemented information on the issue of endogenous fires in coal mines and valid generally binding and internal legislation.
